fllYFE-WRITR ATTACHMENT.

implication filed Jun@ 19, 191.5.

To all 'whom t may concern:

Ille it known that ll, donn W. 1l. Annina,

a' citizen of the `United, States residl i r at li Gales Creek, in the county of Washington i l` he object of my invention is to provide tenor otherwise a. typewriter attachment, of improved construction, which will assist the operator in reproducing, or Copying, on a sheet of paper on the typewriter platen, matter type-writprinted on a separate sheet of paper. f

1n other words, the object is to arovide a device ofthis character which will present the maximum simplicity of construction, and which will be durable, as ivell as positive and automatic, in operation.

1n the accompanying drawing, forming part of my specieation and aliplication, 1 have illustrated the preferred embodiment of my invention capable of carrying ont the underlying principles thereof. ln this drawing, like reference characters denote .corresponding parts throughout the several views.

Theveral views of the drawing may be biieflydesci-.ilid as follows'. 1T igure 1 iS a fragmentary front elevation of a ty ,ewriter-frame and platen, sliowing myiiivention applied thereto; Fig.' 2 is .a sectie/non the line 1li-i3, Fig. 1; Fig. 3 is a side elevation; and Fig. 4 is a section on i the nn@ c nrir. i.

Referring, now, in detailto the drawing: 1 designates the typewriter platen of usual, or any preferred, construction, and forming no part of my invention.

2 is the platenshaft, and 8, 3 theiside members of the typewriter-carriage frame. The platen-shaft 2 carries,toward one end thereof, and exteriorly of the right-hand end frame-member 3, Fig. 1, a sprochetwheel 4, constituting a driven/heel; and, at this end of said plateii-sha'ft, the latter carries the usual knurled hand-wheel or twirler 5.

Suitably detachably carried by each of the typewriter frame-members 3, 3, desirably by means of a strap 6 and set-screws 6, is a vertically-inclined bracket 7, which is, preferably, a fiat plate, the sides of which diverge from the bottom thereof upward, so that the bracket is of least width. at the Specification of Letters Patent.

rateniea nay o, raie.

Serial No. 35,139.

a longitudinally-extending slot -9 disposed parallel with and adjacent one longitudinal edge thereof, as shown in Fig. 2. A plate' 1() is disposed between the brackets 7, 7, and is mounted to slide in these slots 9, and constitutes a sliding guide, for a Vpurpose hereinafter appearing. The Sliding guide 10 is conveniently provided with a thumbhold 11, for ready manipulation thereof. The brackets T, 7 are each also provided,

nearthe tops thereof, with a longitudinally# extending. relatively shorter slot l12 (see Fig. 2), in which Work the shaftsll?, of a pair of juxtaposechrotatable rollers '14, 141",`

which are normally maintained in contiguity and ali the lower ends of the slots 12 by nieans of suitable springs A15, 15.

The slots l) and 12 are parallel, and the slots 9, atthe top, overlap a portion of the slots 12. The rollers 14, 14 and the transverselycurved bridge-plate 8 are so Arelatively positioned that the latter constitutes, in function, a paper-guide to direct the paper clownivard as it passes through the rollers. That is, a horizontal line passing between the rollers will ii'itersect the curved, depending plate 8.

immediately exterior of the supportingbrachet 7, the shaft of the lower roller 14 carries one member v16 of a clutch, which clutch-member 1G axially carries a clutchmember 18 loosely encircling the said shaft of the roller la, and engageable with the other fixed clutelimember 16; whereby,

when said two clutclrrnembers areengaged,`

the sprocket-Wheel 17, driven., through intermediate mechanism, by the driving-vv'heelv 4, is revolved, thereby revolving the roller.

14 and, consequently, the contactingr roller 14..` Carried by the right-hand end t ooking at Fig. 1) of the shaft 13 of said roller 14 `14 and 14 maybe revolved independently of the platen 1, by twirling the thumb-wheel 18. This is a very desirable construction,

since it permits adjustment of the paper between said rollers, without rotating the platen.

Toward the lower end of the supportingbracket 7 a isa shaft 22 carrying two sprocket wheels 23, 24. Engaging the sprocket-wheels 4 and 23 is a sprocket-chain :25, and engaging the sprocket-Wheels 17 and 24 is a sprocketchain 26. It will now -be seen that a sheet of paper disposed between the rollers 14, 14a

will, through the intermediary of the chain of sprockets, described, be fed in a step-by step manner by the step-by-step line-spacing movement of the typewriter-platen 1.

The sliding-guide 10, which may be frictionally-held in the slots 9, 9, or held in any other manner, in any adjusted position, in said slots, is adjusted so as to display between said guide 10 and the roller 14a a line of typewritten matter on the sheet of paper positioned between the rollers 14 and 14a.

From the above description, taken in connection with the drawing, the many advantages of my inventio'r will be apparent. especially to those skilled in the art to which the invention pertains. Among the advantages'may be mentioned, simplicity of construction, automatic operation, and convenlence in attachment to any` standard typewriter. The attachment adds no appreciable or material weight to the typewriter in connection with which it may be used, and is not cumbersome, and presents an attractive appearance, and is of great value in aiding the voperator in copying matter on a typewriter.

`For the purpose of complying with the provisions of the patent statutes of the United States, I have described, with some degree of particularity, the preferred embodiment of my invention; it being understood that all modifications that come within the terms of the appended claim, constitute no departure from the spirit of the invention, and come strictly within the scope thereof.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

In a copy-holder for typewriting machines, in combination with the typewriter platen and typewriter carriage-frame, sup porting brackets removably secured to said frame, each bracket having a short, longitudinally-extending slot toward the top thereof and a relatively longer, longitudinally-extending slot parallel with said firstmentioned slot and, at its upper end, overlapping a portion of said first-mentioned slot, a pair of rotatable rollers having shafts mounted in said short slots and a sliding guide movable in said longer slots.

In testimony whereof, I aflix my signature in presence of two witnesses,

' JOHN IV. H. ADKINS.
